[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0031] First, combine Figures 1-4 The pallet return device according to an embodiment of the present utility model is used for pallet return and has a wide range of applications.

[0032] like Figures 1-4 As shown, the tray return device of this utility model embodiment includes: a pair of conveyor lines 1 and a pair of horizontal push modules 2.

[0033] Specifically, such as Figures 1-4 As shown, in this embodiment, a pair of conveyor lines 1 are arranged adjacent to each other, with a compact structure, reducing the equipment footprint, and are used for pallet loading and unloading respectively. The conveying directions of the pair of conveyor lines 1 are opposite, enabling simultaneous loading and unloading operations, reducing waiting time and improving overall efficiency; a pair of horizontal push modules 2 are respectively arranged oppositely at both ends of the pair of conveyor lines 1. The horizontal push module 2 pushes the pallet 3 on one of the conveyor lines 1 to the other conveyor line 1, and the horizontal push directions of the pair of horizontal push modules 2 are opposite.

[0034] Furthermore, such as Figures 1-4 As shown, in this embodiment, a pair of conveyor lines 1 convey the pallet 3 in the same plane, adopting a planar return flow method, which simplifies the structure, reduces complexity, and reduces the complexity of pallet 3 transfer.

[0035] Specifically, such as Figures 1-4 As shown, in this embodiment, it also includes: a frame 4, which supports and fixes a pair of conveyor lines 1 and a pair of horizontal push modules 2.

[0036] Furthermore, such as Figures 1-4As shown, in this embodiment, the lateral push module 2 includes: a support plate 21, a detection mechanism, a lateral movement mechanism, and a reversing mechanism; the support plate 21 is fixed at one end of a pair of conveyor lines 1 and fixed on the frame 4. The support plate 21 serves as an intermediate platform for the transfer of the pallet 3, connecting the two conveyor lines 1 and providing a stable support platform to ensure that the pallet 3 remains stable during the lateral push; the lateral movement mechanism and the reversing mechanism are fixed on the frame 4, and the detection mechanism is installed on the frame 4 and the support plate 21. The lateral movement mechanism is set along the length direction of the support plate 21; after the detection mechanism detects that the pallet 3 exists on the support plate 21 and has moved into place, the lateral movement mechanism pushes the pallet 3 from one end of the support plate 21 to the other end. After the detection mechanism detects that the pallet has been pushed into place, the reversing mechanism pushes the pallet 3 onto the conveyor line 1. The detection mechanism monitors the position of pallet 3 during the lateral pushing and reversing processes to ensure accurate operation; the lateral movement mechanism completes the transfer of pallet 3 between the two conveyor lines 1; the reversing mechanism pushes the pallet 3, which has been laterally pushed into position, to the target conveyor line 1, completing the final transfer task. Through the coordinated work of the support plate 21, the detection mechanism, the lateral movement mechanism, and the reversing mechanism, the precise, efficient, and stable transfer of pallet 3 between the two conveyor lines 1 is achieved. This not only improves operating efficiency and transfer accuracy but also enhances the stability, safety, and maintainability of the system, while reducing manual intervention, making it suitable for high-efficiency automated production lines.

[0037] Furthermore, such as Figures 1-4 As shown, in this embodiment, the detection mechanism includes: an presence / absence sensor 22 and a pair of position sensors 23; the presence / absence sensor 22 is fixed on the frame 4, and the transmitting end and receiving end of the presence / absence sensor 22 are respectively set at both ends of the support plate 21. The presence / absence sensor 22 detects whether there is a tray 3 on the support plate 21, ensuring that the tray 3 can be identified and subsequent operations can be started after entering the horizontal pushing module 2; a pair of first openings 211 are provided on the support plate 21, and the pair of first openings 211 correspond to a pair of conveying flow lines 1 respectively; a pair of position sensors 23 are respectively installed at the pair of first openings 211 and installed at the bottom of the support plate 21. The position sensors 23 detect whether the tray 3 has moved into place through the first opening 211, that is, at the first opening 211 corresponding to the conveying flow line 1, ensuring that the tray 3 is accurately positioned during the horizontal pushing and reversing process, and providing accurate signals for the horizontal moving mechanism and the reversing mechanism.

[0038] Furthermore, such as Figures 1-4As shown, in this embodiment, the lateral movement mechanism includes a lateral movement cylinder 24 and a push rod 25. The lateral movement cylinder 24 is fixed on the frame 4, and the output end of the lateral movement cylinder 24 is connected to the push rod 25. The push rod 25 is L-shaped. The lateral movement cylinder 24 drives the push rod 25 to move along the length direction of the support plate 21, thereby moving the pallet 3 from one end of one conveying flow line 1 to the other end of the conveying flow line 1. The lateral movement cylinder 24 can be a rodless cylinder, which has a simple structure and can efficiently complete the lateral transfer of the pallet 3, reduce waiting time, and improve overall production efficiency.

[0039] Furthermore, such as Figures 1-4 As shown, in this embodiment, the reversing mechanism includes a reversing cylinder 26 and a push plate 27; a second opening 212 is provided on the support plate 21; the reversing cylinder 26 is fixed on the frame 4 and disposed at the bottom of the support plate 21; the push plate 27 is disposed in the second opening 212 and connected to the output end of the reversing cylinder 26; the reversing cylinder 26 drives the push plate 27 to move, thereby pushing the tray 3 on the support plate 21 to the conveyor line 1. The structure is simple, easy to maintain, operates stably, and has high reliability.

[0040] Working principle: After the pallet 3 is manually placed into the conveyor line 1, the pallet 3 moves forward along the direction of the conveyor line 1. After completing its work at the material picking station, the pallet 3 is conveyed to the support plate 21. When the presence or absence sensor 22 and one of the position sensors 23 detect the pallet 3, it means that the pallet 3 has moved to the designated horizontal pushing position. The horizontal moving cylinder 24 pushes the pallet 3 horizontally until the other position sensor 23 detects the pallet 3, indicating that the pallet 3 has moved to the designated reversing position. The reversing cylinder 26 then pushes the pallet 3 to the unloading conveyor line 1. The unloading conveyor line 1 carries the pallet 3 back to the discharge position. The above operation is repeated. The horizontal pushing mechanism continues to push the pallet 3 to the loading conveyor line 1, and the cycle repeats.

[0041] Above, refer to Figures 1-4 The present invention describes a pallet return device according to an embodiment of the present invention. It adopts a planar return method and only uses a cylinder to push and change direction, reducing the number of mechanisms, facilitating material handling, and has a simple structure, wide applicability, and greatly reducing costs.
